Influence of the type of anion membrane on solvent flux and back diffusion in electrodialysis of concentrated NaCl solutions KU Leuven
The potential of using electrodialysis as a technology for separations in highly concentrated solutions is limited by back diffusion of ions and solvent flux from the diluate to the concentrate. Solvent flux dilutes the concentrate stream while simultaneously back diffusion forms a limitation to reach high ion concentrations. In this study the diffusion flux of sodium and chloride in two different combinations of ion-exchange membranes, namely ...
